Can anyone confirm what harness is required to install the datasystems controller.

I just purchased a ASC680L and H-087G harness.

I took the car apart last night. Once I had removed the glovebox, SRS knee airbag unit, panels etc to gain access to the computer modules I was struggling to identify which unit was the air sus module??

All the previous posts ive seen are for ealier models or 460s and the configurations are slightly different.

I found what I think is the air sus module further underneath and closer to the gearbox tunnel.. it has three plugs but they looked slightly different than the harness (H-087G) i have..

I was wondering if anyone can confirm where the air sus module is located? Or what the correct harness would be? H-087H?

HUGE ****en thank you to whoever can shed some light on this!!

Chur!!

 

Pretty certain (but not 100% because I have an '07) that you have the correct H harness and that the air ECM is located in the same area as the 460. It should be behind the glovebox, way to the right of the AC fan motor. See pic and recommend using a flashlight when looking for yours. There is a lot of useful info in this thread: https://www.clublexus.com/forums/ls-...thread-15.html

I have the speed sensor wire connected to the back of my NAV unit as well. It's more time consuming than connecting the main harness, however, it's worth it to me as it prevents the car from lowering automatically at about 40mph. Good luck!
